ComFlor 100

From the Panels and profiles shallow composite profile range
ComFlor 100, has a very strong profile shape and offers the capability to span up to 4.5 metres without props. Designed particularly for continental european application, the ComFlor 100 also brings considerable benefits to the British designer looking for longer unpropped spans. The profile is not suitable for use with shear stud connectors.

No temporary props
ComFlor 100 can carry wet concrete and construction loads to 4.5 metres without temporary propping, depending on slab depth, thereby leaving a clear area beneath the floor under construction. Further savings of labour and prop hire are also realised.

Large concrete volume reduction
Although a deep slab is required, the ComFlor 100 profile greatly reduces the volume of concrete needed and thus the cost and weight of concrete.

Suitable for traditional construction
ComFlor 100 is suitable to be placed onto masonry walls or standard design non-composite steel beams.

Design information

Volume and weight table notes

1. Deck and beam deflection (i.e. ponding is not allowed for in the table).
2. Deck and mesh weight is not included in the weight of concrete figures.
3. Density of concrete is taken as:
   •  Normal weight (wet) 2400 kg/m²
   •  Normal weight (dry) 2350 kg/m²
   •  Lightweight (wet) 1900 kg/m²
   •  Lightweight (dry) 1800 kg/m

ComFlor 100 is not designed for use with shear studs (i.e. not for composite beam design).

Design notes

Deck material
Zinc coated steel to BS EN 10147:1992, Fe E 280G, Z275, with a guaranteed minimum yield stress of 280 N/mm². Minimum zinc coating mass is 275 g/m² total including both sides.

Quick reference tables
The quick reference load/span and fire design tables, are intended as a guide for initial design, based on the parameters stated below the tables.

Anti-crack mesh
BS 5950: Part 4 currently recommends that anti-crack mesh should comprise 0.1% of slab area. The Eurocode 4 recommendation is that anti-crack mesh should comprise 0.2% of slab area for unpropped spans and 0.4% of slab area for propped spans. Panels and Profiles in conjunction with The Steel Construction Institute, has agreed to modify the requirement with regard to anti-crack mesh, to comply with the Eurocode 4 recommendations. Accordingly, the mesh shown in the quick reference tables complies with EC4 and the design program defaults to these values. Where EC4 mesh rules are used, the mesh may be reduced midspan. The reduced British Standard mesh values may still be used by overriding this default in the design program. Mesh top cover must be a minimum of 15 mm, and a maximum of 30 mm. Mesh laps are to be 300 mm for A142 mesh and 400 mm for A193, A252 & A393 mesh.

Fire
For details of the performance of composite slabs under a fire condition with nominal anti-crack mesh, please refer to the quick reference fire load tables.
